Analysis
7. Analysis#
The analysis package collects modules and tools for high-level analysis of Belle II data. With analysis modules you are able to open mdst format files, create final state particles, and build more complicated decays. With these particle decay candidates, you can use high level tools such as Tree Fitter, Flavor Tagger, and the Full event interpretation (FEI).
Tip
For a series of hands-on introductory lessons, take a look at Section 3.4.
The core data objects of the basf2
analysis package, are the Particle class, and the ParticleList class.
Almost all analysis modules are concerned with the manipulation of ParticleList s.
Examples of analysis steering files can be found in tutorial directory of analysis package:
